                      REPORT OF INDEPENDENT ACCOUNTANTS 

To the Board of Directors and Stockholders of 
Beacon Properties Corporation: 

   We have audited the accompanying statement of excess of revenues over 
specific operating expenses of the Rosslyn Acquisitions in Rosslyn, Virginia 
(the "Properties") for the year ended December 31, 1995. This financial 
statement is the responsibility of the Properties' management. Our 
responsibility is to express an opinion on this financial statement based on 
our audit. 

   We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the statement of excess of revenues 
over specific operating expenses is free of material misstatement. An audit 
includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the statement. An audit also includes assessing the accounting 
principles used and significant estimates made by management, as well as 
evaluating the overall financial statement presentation. We believe that our 
audit provides a reasonable basis for our opinion. 

   As described in Note 2, this financial statement excludes certain income 
and expenses which would not be comparable with those resulting from the 
operations of the Properties after acquisition by Beacon Properties 
Corporation. The accompanying financial statement was prepared for the 
purpose of complying with the rules and regulations of the Securities and 
Exchange Commission and is not intended to be a complete presentation of the 
Properties' revenues and expenses. 

   In our opinion, the financial statement referred to above presents fairly, 
in all material respects, the excess of revenues over specific operating 
expenses (exclusive of income and expenses described in Note 2) of the 
Rosslyn Acquisitions in Rosslyn, Virginia for the year ended December 31, 
1995 in conformity with generally accepted accounting principles.

                    NOTES TO STATEMENT OF EXCESS OF REVENUES
                       OVER SPECIFIC OPERATING EXPENSES 

1. Organization and Significant Accounting Policies: 

   Description of Properties 

   The Rosslyn Acquisitions (the "Properties") are located in Rosslyn, 
Virginia, consisting of two office buildings together encompassing 
approximately 666,000 square feet. Beacon Properties Corporation intends to 
acquire the entire fee interest in the Properties. 

   Rental Revenues 

   Rental income is recognized on the straight-line method over the terms of 
the related leases. The excess of recognized rentals over amounts due 
pursuant to lease terms is recorded as accrued rent. The impact of the 
straight-line rent adjustment increased revenues by approximately $505,000 
for the year ended December 31, 1995. 

   Risks and Uncertainties 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of revenues and expenses during 
the reporting period. Actual results could differ from those estimates. 

2. Basis of Accounting: 

   The accompanying statement of excess of revenues over specific operating 
expenses is presented on the accrual basis. This statement has been prepared 
in accordance with the applicable rules and regulations of the Securities and 
Exchange Commission for real estate properties acquired or to be acquired. 
Accordingly, the statement excludes certain historical income and expenses 
not comparable to the operations of the properties after acquisition, such as 
management fees, depreciation, amortization, and interest expense. 

3. Description of Leasing Arrangements: 

   The commercial and office space is leased to tenants under leases with 
terms that vary in length. Certain of the leases contain real estate tax 
reimbursement clauses, operating expense reimbursement clauses and renewal 
options. Minimum lease payments to be received during the next five years for 
noncancelable operating leases in effect at December 31, 1995 are 
approximately as follows: 



 Year Ending December 31, 
- -------------------------- 
                           
1996                          $15,485,000 
1997                           14,408,000 
1998                           13,952,000

Thereafter                     26,860,000 


   As of December 31, 1995, two tenants occupied approximately 25% of 
leasable square feet and represented approximately 24% of total 1995 revenue.

                    NOTES TO STATEMENT OF EXCESS OF REVENUES
                        OVER SPECIFIC OPERATING EXPENSES

1. Organization and Significant Accounting Policies: 

   Description of Properties 

   The New England Executive Park (the "Properties") is located in 
Burlington, Massachusetts consisting of nine office buildings together 
encompassing approximately 817,000 square feet. Beacon Properties Corporation 
intends to acquire the entire fee interest in the Properties. 

   Rental Revenues 

   Rental income is recognized on the straight-line method over the terms of 
the related leases. The excess of recognized rentals over amounts due 
pursuant to lease terms is recorded as accrued rent. The impact of the 
straight-line rent adjustment decreased revenues by approximately $59,000 
for the year ended December 31, 1995. 

   Risks and Uncertainties 

   The preparation of financial statements in conformity with generally 
accepted accounting principles requires management to make estimates and 
assumptions that affect the reported amounts of revenues and expenses during 
the reporting period. Actual results could differ from those estimates. 

2. Basis of Accounting: 

   The accompanying statement of excess of revenues over specific operating 
expenses is presented on the accrual basis. This statement has been prepared 
in accordance with the applicable rules and regulations of the Securities and 
Exchange Commission for real estate properties acquired or to be acquired. 
Accordingly, the statement excludes certain historical income and expenses 
not comparable to the operations of the Properties after acquisition, such as 
interest income, management fees, depreciation, amortization, and interest 
expense. 

3. Description of Leasing Arrangements: 

   The commercial and office space is leased to tenants under leases with 
terms that vary in length. Certain of the leases contain real estate tax 
reimbursement clauses, operating expense reimbursement clauses and renewal 
options. Minimum lease payments to be received during the next five years for 
noncancelable operating leases in effect at December 31, 1995 are 
approximately as follows:

                       STATEMENT OF EXCESS OF REVENUES 
                       OVER SPECIFIC OPERATING EXPENSES 

                     FOR THE YEAR ENDED DECEMBER 31, 1995 

                                     F-9 
 

                      REPORT OF INDEPENDENT ACCOUNTANTS 

To the Board of Directors and Stockholders of 
Beacon Properties Corporation: 

   We have audited the accompanying statement of excess of revenues over 
specific operating expenses of the 10960 Wilshire Boulevard in Westwood, 
California (the "Property") for the year ended December 31, 1995. This 
financial statement is the responsibility of the Property's management. Our 
responsibility is to express an opinion on this financial statement based on 
our audit. 

   We conducted our audit in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the statement of excess of revenues 
over specific operating expenses is free of material misstatement. An audit 
includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the statement. An audit also includes assessing the accounting 
principles used and significant estimates made by management, as well as 
evaluating the overall financial statement presentation. We believe that our 
audit provides a reasonable basis for our opinion. 

   As described in Note 2, this financial statement excludes certain income 
and expenses which would not be comparable with those resulting from the 
operations of the Property after acquisition by Beacon Properties 
Corporation. The accompanying financial statement was prepared for the 
purpose of complying with the rules and regulations of the Securities and 
Exchange Commission and is not intended to be a complete presentation of the 
Property's revenues and expenses. 

   In our opinion, the financial statement referred to above presents fairly, 
in all material respects, the excess of revenues over specific operating 
expenses (exclusive of income and expenses described in Note 2) of 10960 
Wilshire Boulevard in Westwood, California, for the year ended December 31, 
1995 in conformity with generally accepted accounting principles.

            PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION 

   The following unaudited pro forma Condensed Consolidated Balance Sheet of
Beacon Properties Corporation (the "Company") as of September 30, 1996, is
presented as if the acquisition of the Rosslyn, Virginia Portfolio and the
Pending Acquisitions had occurred on September 30, 1996. The pro forma Condensed
Consolidated Statements of Operations are presented as if the Offering, the
acquisition of the Properties acquired since January 1, 1995 (including
Perimeter Center, New York Life and the Fairfax Virginia Portfolios) and the
closing of the MetLife Mortgage loan, the acquisition of the Pending
Acquisitions and related assumption of debt had occurred as of January 1, 1995;
the Company qualified as a REIT, distributed all of its taxable income and,
therefore, incurred no income tax expense during the period.

   In management's opinion, all adjustments necessary to reflect the above 
discussed transactions have been made. The unaudited pro forma Condensed 
Consolidated Balance Sheet and Statement of Operations are not necessarily 
indicative of what actual results of operations of the Company would have 
been for the period, nor does it purport to represent the Company's results 
of operations for future periods.
